• In doing so , the amount of insulated sound in all parts of the fender structure ( e . g . , the civil work , doors and windows ) should be identical
  所谓等隔声概念就是整个围护结构的各个部分（如土建结构部分和门、窗等部分）的隔声量应相当。
• The conclusions are drawn by analysis : the sound insulation performance of structure is improved by using flexible viscoelastic materials ; otherwise it is complicated to sound insulation for incidence angles and the thickness of materials ; for multi - layered compound structure , it is important to choose flexible viscoelastic materials as external rubber , which can gain good insulative effect
  分析表明：软质阻尼材料能明显改善结构的隔声性能；相对来说入射角度和材料的厚度对隔声性能的影响比较复杂；而对于多层复合结构而言，面层橡胶的选取尤为重要，一般采用软质橡胶材料来得到大的隔声量。
• Again we take an imported 500 kw engine unit as the example . in this case baffle boards are stuck on walls inside the engine room , meanwhile baffle boards are also used as suspended ceilings . by doing so not only the amount of insulated sound of the fender structure is increased , but the reverberant sound in the engine room is also depressed ( normally by 3 to 5db )
  我们仍以一台500kw进口机组为例，油机房室内墙面设计为贴吸音板，同时用吸音板吊顶，经过这样的吸声处理后既增加了围护结构的隔声量，又可降低油机房内的混响声，一般可有3 ~ 5db （ a ）的效果。
• Passages reserved for connecting the engine room to the outside ( e . g . , the cooling fan outlet , the exhaust outlet , the ventilation outlet , etc . ) must be designed as muffling passages , whose insertion loss should also be equivalent to the sound insulation amount of the fender structure . only in this way can the environmental noise outside the engine room live up to the standard
  为机房与外界相通而预留的通道（如冷却风扇出口、发动机排气出口、机房通风换气口等）必须设计成消声通道，其插入损失也应与围护结构的隔声量相当，只有这样做才可保证机房外的环境噪声达标。
• Based on the sound wave transferring theory of infinite elastic and viscoelastic materials with the method of transferring matrix , the formulas of transmission coefficient and the level of sound insulation are gained , which consider shearing strength in the rubber , and the sound insulation properties of compound structures are discussed in condition of oblique incidence
  摘要基于无限大弹性体和粘弹性体的波传递理论，采用传递矩阵的方法，对斜入射情况下的透射系数和隔声量进行了理论推导，考虑了声波在橡胶中传播所产生的剪切力，并就单层复合结构的隔声性能进行了详细的研究，进而也分析了多层复合结构的隔声性能。
